' T0 all whom t may concern Be it known that I', LAWRENCE D. MoR- ToN, acitizen of the United States of America, residing at Sandusky, in thecounty of Erie and State of Ohio, have invented certain new and usefulImprovements in yPackage-Sealing Machines, of which the following isaspeciication, reference being had therein to the accompanying drawings.

It is the object of the invention to obtain a construction of machineadapted to facilitate the operation of closing and sealing theoverlapping vliapsA of a .paper board carton or package, and theinvention comprises various features of construction as hereinafter setforth.

In the drawings: Figure 1 is a vertical central section through themachine; and Fig. 2 is a side view illustra-ting the operation.

The package or carton which is closed and sealed upon my improvedmachine comprises rectangular sides hinged to each other at the cornersand projecting flaps from opposite ends thereof. In knock-down positionthe sides and end flaps lie in the same plane, but in setting up the boxthe sides must first be adjusted to rectangular position and theendl'laps then turned down to form the bottom. Furthermore, these endflaps which overlap each other must be permanently secured by someadhesive material, and to make a good joint should be pressed togetherby the adhesive While hardening. With my invention provision is made,first, for holding the sides of the boX in rectangular position whilethe end flaps are being pasted; and second, for clamping and holding thepasted Haps until the adhcsive sets.

In detail, A'is a central pivot plate secured to the floor and formingla pivot bearing for a. post B.

C is a frame secured to the post B and comprising radial arms C at thetop and bottom of said post and annular frames C attached to said arms.The lower frame C2 is additionally supported by caster wheels l) whichpermit of rotating the frame With slight vertical resistance. Y

l are posts or standards secured to the sides of the bottom frame C2 andhaving a. hinge connection therewith, permitting of movement into anoblique or angular posi- 'Enron.;A

tion. This is preferably formed by a socket casting or fitting F mountedupon the frame C2, one side of which F is inclined, as sho\vn.

G are forms adapted to lit within the package to be sealed and Which aredetach- -ably supported upon the posts E.

H are heads supported upon the upper frame C2 in a position to be inalinement With the' heads (i when the posts E are in upright position.The heads H are vertically adjustable, being secured to Athe frame C2 bysprings I and being centrally guided by brackets J tclescopicallyengaging complementary guides K upon the upper frame C2. The guides Kare bifurca'ted, and between the fureations lthereof is pivotallysecured a lever L having a cam portion L adapted to bear upon a roller Min the bracket J. The arrangement is such that ay rocking of the lever Lwill cause the cam L to depress the head Hagainst the ltension of thesprings I and to move it into clamping contact With the head Gr.

,To support the boX to be sealed during the operation of turning downthe flaps an adjustable rest N `issecured to each standard E. Thispreferably comprises a sleeve upon said standard secured by a set screwN, and having arms N2 extending from opposite sides thereof. l

On the top of the head H there is a member H which carries the guidesfor registering the package with the head. This member H is adjustablysecured to the head H by virtue of a bolt and slot connec-` tion, theslot, l, being in the member H and the bolt 2, passing through the slot,is securely fastened in the head H. The head of the bolt when the sameis in its secured position prevents the separation of the parts.

In operation, a pile of the knock-down packages is placed adjacent toone side of the machine, and the operator taking his position inproximityV to this pile successively sets up and seals the packages asfollows: The' standard E is first turned down iw v o n to its initialposition, and the time which operator to turn down the Iiaps againstthis head. As has been stated, the iiaps upon adjacent 'sides overlapeach otherand to permanently secure these together a suitable paste orglue is applied to the outer face of the fiap rst turned dowlnand 'theoverlapping 4.iiaps are then folded into contact therewith. After thisoperation the standard E is moved into upright position, and the head His clamped l thereagainst by drawing down the lever L. During this op--1 eration the guides O insure proper registration of the heads (ir andH, so that when clamped,4 all'portions of the overlapplng glapsarefirmly pressed together; After enf-'giigng one box in the mannerdescribed, the frame C is slightly rotated to bring another -standardinto convenient position, and the `same`goperation is repeated. vThis 1scontinued until the box first sealed 1s returned has elapsed between theoriginal sealing and the return of the package is suflicient for thecomplete setting of the glue or adhesive,A

Thus the operator, after unclamping the .lever L, may return thestandard E into 1nclined position, remove the finished box and l 'jreplace another blank upon the head G.

To adapt my machine for dili'erent sizes of box or package, the headsGrare removable, as has been described, and a different set of heads maybe used for each size of box. The heads H do not, however, requirereplacement, as the guides O may be adj usted to suit the differentsizes.

What I claim as my invention is: 1. The combination with a revolublecarrier of a series of clamping heads mounted thereon, a series ofcoperating heads also mounted on said carrier, each being movable intoand out of registration with its corresponding clamping head, guides forregistering said heads with each other, and independent clamping meansfor the respective pairs of clamping heads..

2. The combination with" a revoluble standard of a series ofblank-holders mounted thereon, each provided with a head insertiblewithin the package, against which the end Haps may be folded, adjustablesupports secured to each standard for supporting the package, a seriesof clamping heads corresponding to said blank-holders mounted on saidcarrier, means permitting the adjustment of each blank-holder intoregistration with it-s clamping head, and independent actuating meansfor the respective clamping heads.

3. The combination with a revoluble carrier of aseries of standardsmounted thereon and adjustable from an inclined` to a vertical position,a head mounted' on each standard over which the box to be sealed may besleeved in the inclined position of Svthe standard,. means forsupporting the box upon the standard in position for the turning of itsend flaps against said-head, a series of clamping heads secured to saidcarrier and respectively in registration with said standards when inupright position, and clamping levers for depressing said clamping headsagainst the heads of said standards.

4. The combination with a revoluble carriei of upper and lower annularframes up n said carrier, a series of standards having hinged connectionwith said lower frame, permitting of adjustment from a vertical to aninclined position, a form on each standard insertible into a box to besealed and forming a headagainst which the end flaps of said box may befolded, a support on said standard for holding the blank in position forthe folding of its flaps, clamping heads vertically, adjustably mountedon said upper annular frame in position for registration with said lowerheads when the supporting standards thereof are in vertical position,and` clamping levers for v actuating said clamping heads.
